Review on Samsung Cellular Unlocked International Charging Computers & Tablets for Tablets by Adam Matthews

Suitable for web search and email. Good for value. The battery seems to be enough. For those who want to connect to AT&T, you need to set the APN settings and set the phone line to data only (no voice). I went to the AT&T store and, as another person said, tried several SIM cards which showed communication with the tower, but I couldn't receive any data over the cellular network. He worked for AT&T for many years but was stuck in a dead end. Leave the card installed to see if it would connect in an hour. Vain. Tried many APN settings suggested online. Vain. Then I discovered that the APN settings on my old AT&T banned Tab 4 was the ticket to access my data-only phone connection/number. This may work for people with an AT&T cell phone number.
